Product Introduction

GB/T 4171 steel plate introduction:
GB/T 4171-2008 atmospheric corrosion resisting structural steel are produced in the grades and qualities: Q355GNH, Q310GNH, Q295GNH, Q265GNH, Q235NH, Q295NH, Q355NH, Q415NH, Q460NH, Q500NH, Q550NH.
GB/T4171-2008 Q235NH, Q355NH, Q355GNH steel plates are having many excellent features to offer. This has made them to be very much high in demand. Those GB/T4171 steel plates are good dimensional accuracy, high tensile strength, withstanding high temperature and heavy loads, high durability, high flexibility, rugged construction, good surface finishes. It is also having more features like anti-corrosives, general corrosion resistance ability, and crevice corrosion and stress corrosion cracking resistance ability.
